Detailed description of the invention
In conjunction with the accompanying drawings, the present invention is further detailed explanation. These accompanying drawings are the schematic diagram of simplification, and basic structure of the present invention is only described in a schematic way, and therefore it only shows the formation relevant with the present invention.
(embodiment 1)
As shown in Figure 1 to Figure 3, the automatic die clamping device of the present embodiment comprises housing 1 and the first hydraulic cylinder 2, first piston 3, the second hydraulic cylinder 4, the second piston 5, spring 6, elastic component 7 and the stopping means 8 that are arranged on housing 1 inside;
On the first hydraulic cylinder 2 and the second hydraulic cylinder 4, be respectively arranged with the first hydraulic fluid port 21 and the second hydraulic fluid port 41;
First piston 3 is positioned at the first hydraulic cylinder 2 inside, and the piston rod of first piston 3 is connected with the second hydraulic cylinder, and the inside of first piston 3 is provided with along the through hole of its piston rod direction, and this through hole is communicated with the second hydraulic fluid port 41 of the second hydraulic cylinder 4;
The second piston 5 is positioned at the second hydraulic cylinder 4 inside, and the other end of the piston rod of the second piston 5 is provided with and compresses boss 51;
Between the second piston 5 and the second hydraulic cylinder 4, be provided with block rubber 71;
Between the second hydraulic cylinder 4 and housing 1, be provided with spring 6;
The second hydraulic cylinder inside is provided with spacing preiection 81, and spacing preiection 81 limits the stroke of the second piston 5, controls the second piston 5 and does not cross the second hydraulic fluid port 41.
The automatic die clamping device of the present embodiment is arranged on the surface of die bottom plate 9, and as can be seen from Figure 2, the edge of die bottom plate 9 and mould 10 all offers one section of longitudinal groove; Hydraulic cylinder 2 is interior while starting to be filled with hydraulic medium when first, and first piston 3 drives the second hydraulic cylinder 4 to move right, and this stage second piston 5 is because the effect of block rubber 71 does not move; In the time that first piston 3 walks to low order end, the piston rod of the second piston 5 enters in the groove at die bottom plate 9 and mould 10 edges, pressure in two hydraulic cylinders continues to rise, the second piston 5 pushes block rubber 71 and moves upward, the compression boss 51 of the second piston 5 piston-rod lower ends is pressed on mould 10 on die bottom plate 9, completes mold cramping. When dismounting, remove two fluid pressures in hydraulic cylinder, the second piston 5 unclamps mould 10 automatically, and spring 6 promotes the second hydraulic cylinder 4 and leaves mould 10 with the second piston 5, facilitates more mold exchange 10 of follow-up equipment.
Taking above-mentioned foundation desirable embodiment of the present invention as enlightenment, by above-mentioned description, relevant staff can, not departing from the scope of this invention technological thought, carry out various change and amendment completely. The technical scope of this invention is not limited to the content on description, must determine its technical scope according to claim scope.
